Tiptap: Extensions Lists not work

[pk-pressf1]

When I connect BulletList or OrderedList, I see the following error
"SyntaxError: No node type or group 'list_item' found (in content expression 'list_item+')"

For lists, be sure to import ListItem
import {BulletList, OrderedList, ListItem } from 'tiptap-extensions'

When adding ListItem, I get another error

Full component code if needed, but this is almost identical to what's in the docs

<template>
  <div>
    <editor-menu-bar :editor="editor" v-slot="{ commands, isActive }">
      <cv-button
        icon="list-ul"
        :class="{ 'bg-gray-800': isActive.bullet_list() }"
        @click="commands.bullet_list"
      />
    </editor-menu-bar>
  </div>
</template>

<script>
import { Editor, EditorContent, EditorMenuBar } from "tiptap";
import { BulletList, ListItem } from "tiptap-extensions";

export default {
  components: {
    EditorContent,
    EditorMenuBar
  },
  props: {
    content: {
      type: [String, Object],
      default: ""
    }
  },
  data() {
    return {
      editor: new Editor({
        extensions: [new BulletList(), new ListItem()],
        content: this.content,
        onUpdate: ({ getHTML }) => {
          this.$emit("input", getHTML());
        }
      })
    };
  },
  beforeDestroy() {
    this.editor.destroy();
  }
};
</script>

I've also tried only importing without adding to the extensions array both with and without OrderedList

After importing ListItem, try to add as a new extension on your data as well. I was having the same issue as you and it worked.
